PROMISE Technology Announced Compatibility with Apple macOS Big Sur and M1 Chip Powered Mac To Provide the Peace of Mind to Pegasus Series Customers

Santa Clara, December 15, 2020 -- PROMISE Technology Inc., the leading storage solutions provider, today announced that its Pegasus3, Pegasus32, Pegasus R4i, Pegasus J2i, and newly announced PegasusPro are now compatible with Apple macOS Big Sur and the new M1 chip powered Mac. Additionally, these Pegasus models are compatible with Intel-based Mac upgrading to Big Sur, making it possible for both new and existing customers to upgrade their devices this holiday season.

macOS Big Sur is the most significant upgrade to this popular operating system since the introduction of Mac OS X in 2001. In addition to a major redesign of the user interface, macOS Big Sur is the first operating system to be exclusively made for the first ARM-based custom system-on-chip (SoC), the M1 which has been entirely developed from the ground up. The chip will also be compatible with PROMISE’s recently released advanced PegasusPro Fusion Storage system, which was announced as the world’s first storage system to combine both Direct Attached Storage (DAS) and file-based Network Attached Storage (NAS).

PROMISE Pegasus Series is always a pioneer to keep the pace with technology updates, which is why Pegasus Series is well known and widely adopted by creative professionals. PROMISE R&D engineers started researching the compatibility with the new macOS Big Sur and M1 chip ahead of time to meet the expectations of Pegasus users worldwide to ensure their storage devices are compatible with these two new upgrades, and to enjoy the peace of mind. Our persistent endeavours mean the existing Pegasus installations and new customers will continue rich media workflow without interruption, ” said Michael Lin, CIO and R&D Head of PROMISE Technology.
